Title: File control system
Inventor: SHIMAZU KAZUYUKI
IPC: G06F7/22
Filed: 1988-07-01
Abstract: PURPOSE:To shorten a processing time by completing initialization processing concerning an index part, which corresponds to an arbitrary file, only by updating a retrieving information record. CONSTITUTION:The index information record is provided in an index by an index total initializing means and the revision number of the whole index and the plural revision numbers to correspond to plural files are set. Then, since the index part initializing means updates these two revision numbers, the index part to correspond to the arbitrary file is initialized. A pointer value registering means registers a pointer value into an index key record and the revision number of the whole index for an index information record is copied into the index key record. A pointer value deciding means compares the revision number to correspond to the file in the index information record and the revision number in the index key record and decides whether the pointer value in the index key record is effective or not.

IPC: H04N5/335
Filed: 1985-07-23
Abstract: PURPOSE:To pickup an image of a moving object without blurring by dividing an optical image into two, applying photoelectric conversion to the divided optical images and controlling the drive start time between two video signals and the relation of position on two images. CONSTITUTION:An optical image converged by an optical means 11 is divided into two by a spectroscope 12, the divided images are led to solid-image pickup elements 13, 14, where they are converted into electric signals. In this case, the solid-state image pickup elements 13, 14 are driven by a drive signal generating circuit 20, since the drive signal to the solid-state image pickup element 14 is retarded by a time difference control circuit 21 with a time difference, the solid-state image pickup element 14 starts its operation with a delay more than the solid-state image pickup element 13. When the moving object is picked up by the solid-state image pickup device, a signal delay circuit 17 positions the images and the result is detected by a difference signal circuit 18, then a signal in response to the movement of the mobile object is outputted from an output terminal 19. Thus, the presence of the mobile object is detected by using the signal from the output terminal 19.

Filed: 1992-06-02
Abstract: PURPOSE: To provide an optical switch for not sacrificing the characteristics of SEED by constituting the optical switch by serially connecting a pull-down device provided with a signal means for a trigger and a voltage controlled optical modulation element. CONSTITUTION: When the clock pulses P3 of a fixed amplitude are applied, the state of this optical switch is not changed until an optical excitation carrier is balanced. When the optical excitation carrier is balanced once, a SEED diode D3, that is the optical modulation element, is discharged. Then, a full voltage drop appears on the SEED diode D1, the absorbing action of the diode D1 becomes high and the reflectance of the diode D3 becomes high. Thus, the reset of a device is completed by the clock pulses P3 . If the next pulse of a signal, pulse P1 is sufficiently dominant, the diode D1 is completely discharged, the diode D3 is completely charged, the reflectance becomes low, the next pulse P3 becomes low and the switching of the optical switch is completed.
